Pocket Rockers employed the use of "cart" tapes, which are very similar to the eight-track tapes of the 1970's and 1980's. Each side of each tape contained one song, usually around 2 minutes in length (some songs were faded out before the song actually finished). The player had a switch that let the listener change between the two available tracks, and a small knob on the front controlled the volume. A headphone jack was on the side, as well as a slider to eject the tape.

Each Pocket Rocker tape was incredibly small, only measuring around 1.5" x 1.25". This, along with the small, durable player and bright colors, made the Pocket Rockers very popular with kids for their short lifetime. Powered by AA batteries, the players lasted for quite a long time.

Of course, after 1992Fisher-Price no longer supported Pocket Rockers, and the production of new tapes containing new music was halted. Below is a final listing of each Pocket Rocker tape that was sold.
